CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 342,381, dated May 25,1886.

Application filed March 27, 1886. Serial No. 196,825. (No model.)

To aZZ whom, it may concern.-

Be it known that we, WILLIAM H. Orr and ELI R. MoKmzncitizens of theUnited States. residing at Boston Station, in the county of GrawfordandState of Indiana, have invented a new and useful Improvement inCar-Couplings,of which the following is aspecification, reference beinghad to the accompanying drawings.

Our-invention relates to an improvenientin car-couplings; and itconsists in the peculiar construction and combination of devices thatwill be more fully set forth hereinafter, and particularly pointed outin the claim.

In the drawings, Figure l is a perspective view of our invention. Fig. 2is a horizontal sectional view of the same.

A represents the draw-head, which is provided with the usual opening, B,for the reception of the coupling-link O, and with a horizontal opening,D, which extends across the inner end of the opening B.

E represents a couplingjaw, which is provided on its front side with asubstantially V-shaped opening, 6, thereby forming arms 6 and e", thelatter of'which is longer than the former, and is provided at its outerend, on its inner side, with an extending hook or pin, a, which works ina horizontal opening, A, which is made in the draw-head near the outerend thereof.

F represents a turning-shaft, which extends vertically through anopening in the drawhead,and is keyed or otherwise rigidly secured to therear end of the jaw E, and forms a fu1- cruin therefor.

On one side of the draw-head is secured a pair of vertically-alignedkeepers, Gr, one of the said keepers being located above and the otherbelow theouter side of the jaw e. The vertical shaft F extends to thetop of the car, on the front side thereof, and is provided at its upperend with a crank or wheel, F, and is journaled near its upper end inabracket,f, which extends from the front side of the car.

H represents a vertically-movable detentrod, which works in keepers I,that are secured on the front side of the car, and the lower end of thesaid rod is bent outwardly and then downwardly, and thereby adapted topass through the keepers B and bear against the outer sides of thejaw.

The operation of our invention is as follows: In order to couple thecars,the detent-rod I is raised and the jaw swung outwardly to theposition shown in dotted lines in Fig. 2. \Vhen the link enters thedrawhead,it strikes against the inclined sides of the arm 6 of thecoupling-jaw and partly rotates the latter, causing the hook or pin 0"to enter the opening A in rear of the front end of the coupling, andthereby prevent the latter from being withdrawn. The detent-rod is thenlowered and caused to bear against the outer side of the oouplingjaw, ashereinbefore described, and thereby prevent the cars from becomingaccidentally uncoupled.

Having thus described our invention, we claim- V The combination ofthedraw-head, the coupling-jaw E, fuicrumed therein,and having the opening6 and the pin or book 6 and the detent for locking the coupling-jaw inthe drawhead, for the purpose set forth, substantially as described.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in presence of two witnesses.
